System Error Codes
System Error Codes are defined errors and error codes that are utilized by programmers when their software has an issue. They can be displayed by a computer to users in response to software problems or hardware issues, or even certain kinds of user input. System error codes are displayed as an acronym, along with a description and suggestion of what to do next.
These error codes can be seen on the Internet when a website isn’t accessible, or if there is an internal server issue or data base issue. On local machines the error could be as simple as a “file too long” which can be resolved by changing the name of the file or more complex such as “no space left on the disk.” In this scenario you might have to close some applications (to remove swap files), delete some files, or buy an additional hard disk.
Other system issues can be as serious as “fatal error,” where a program has decided to stop and give up, or as mild as a warning that something isn’t quite right in an operation. The header file errno includes error codes for virtually every possible error on the GNU/Hurd operating system.
These errors can be as simple as “text file busy,” where the operation is trying to modify a read-only file or as complex as “broken pipe.” These errors could also mean that the process trying to operate on the resource has been interrupted by a signal such SIGPIPE and not properly handled.
